Luke Donald has admitted that the crowd at Medinah Country Club will make it difficult for Europe to retain the Ryder Cup next week.
The Brit, who lives 30 miles away from the course, believes that the fans in Chicago will provide a big boost for their rivals.
Donald told Sky Sports News: "It'll be extremely raucous. I've played in three Ryder Cups and I think this is the biggest city in terms of the location and that'll make it a little bit more fun.
"I think the fans will get behind this Ryder Cup and it'll make it tough for the Euros. They're going to be on the Americans' side, they'll be cheering hard but they're a fair crowd and hopefully they'll respect both teams.
"The home team's biggest advantage is the crowd support and if we can take that away a little bit, not just through my relationship with Chicago, but also playing well then that will be a slight benefactor for us."
Donald will be competing in his fourth Ryder Cup for Europe.
